SPECIFICATION forming'. part of Letters Patent No. 294,503, dated March 4, 1884.

- Application filed June 2S, 1883. (No model.)

Be it known that I, J oHANNEs PERssoN, a citizen of Sweden, and a resident of N ew York, inthe county of New York and State of New York, have invented a new and useful Improvementin Waste-Pipe Ventilators, of which the following is a specification.

The obj ect of my invention to provide an improved device for leading ott' the foul air from water-closets, &c., to above the roof of a building, and to facilitate the discharge of solid or liquid matter to the sewer; and it consists in the construction and combination of the sev- -eral parts, as will be hereinafter described and and claimed.

The figure in the accompanying drawing represents a general sectional elevation of an apparatus constructed according to my present invention, and partly broken out to show its location with reference to the ground, the cellar, one of the floors above, and the roof.

S is the sewer; C, the cellar-floor; F, one of the iioors above, and R the roof. A'is the drain-pipe, and B the ordinary vertical wastepipe, extending above the roof R.- 'Ihe hopper H of the ordinary water-closet is connectedto the waste-pipe, as usual, by means of a V-joint, b, attached to the waste-pipe. The hopper H is not provided or connected with the ordinary S-trap, (the latter being dispensed with,) but its leg or lower end inclines Alaterally from the hopper in line with and enters into the V-j oint b of the waste-pipe B, (the ordinary water-pans G being considered sufcient-water seal where ample means for ventilation are provided,a s will presently appear.) From the cellar-floor C, to and through the roof R, is a large air-pipe, D, arranged to surround the waste-pipe B and a portion of the V-joint Z, and within the said pipe D extends upward from the joint Z1 a short pipe, b. The lower end of the air-pipe Dis provided with notches or projections c, to admit air to the pipe. The air entering, as indicated by the arrow 1, permits a rapid upward draft through the pipe D, from the upper end of which latter it escapes into the outer air through perforations and notches e e in the sides of the top cover, E, and the edge of its funnel-shaped central opening, E', respectively, as indicated by the arrows 2. The funnel E is covered by an ordinary cap, F, made in the shape of an inverted funnel. The air-current in the pipe D causes a partial vacuum in the pipe b of the hopper H, thereby causing the foul air from the hopper to also enter the pipe D in the direction indicated by arrow 3, and to escape with the air-current through the upper end of the air-pipe.

The drain-pipe A is connected with the sewer S by means of a short pipe, A', anged on that end which enters the sewer. This joint A is preferably made of copper or brass, and has a hinge valve or gate, I, closing its end. A little distance inside of the hinge-valvel I is hinged or pivoted within the pipe another gate or valve, J, which fits, as nearly as practicable, tight, while allowing it to'swing forward when acted on by the pressure of liquid and solid matter passing through the drainpipe. The valve J has two lugs or projections, i; between which is pivoted a roller, which, when the valve J is pressed forward to assume the position shown in dotted lines, will roll lagainst the inner surface of the valve I and swing the latter out in its dotted position, thus sewer S. YVhen the pressure on the valves ceases, they will assume their vertical or normal position, the valve I tightly closing the end of the drain-pipe joint A. The pressure of gasesfroni the sewer will naturally have the tendency of keeping the valve I closed,

allowing the escape of the foul matter into the thus preventingv gases from rising through the Y drain-pipe A and waste-pipe B. Under ordinary circumstances, and in orderV to prevent any possibility of the draft in the sewer striking the edge of the valve I from the inside, or, as indicated by arrow 4, the end flange, a, of the pipe A is made much wider than the valve I. The object of the inner valve, J, is to prevent the matter in the drain-pipe from coming in contact with the inside of the valve I in passing out through the end opening into the sewer, thereby keeping the saidvalve comparatively clean and capable of forming a close contact with its valve-'seat for obvious reasons.

IOO

Waste-pipe connection I), provided with the 3. ThehopperH, having alaterally-inclined npwardlyprojeating open pipe b, the wastepipe B, and the air-pipe D, inolosing the said pipes B and b', the said pipe D being` open at its upper end, and having also openings c at its lower end, substantially as and for the purpose set forth.

2. In combination with the Waste-pipe B and drain-pipe A, the fianged joint A, provided with the end valve, I, and the valve J, pvoted inside of the said joint A', the said valve J being provided with means i, operati ng against the valve I to open the latter simultaneously with the former, substantially as and for the purpose set forth.

discharge-leg entering into and in a straight line with the waste-pipe, in combination with the pipe b', waste-pipe B, and surrounding airpipe D, all constructed and arranged substantially as and for the purpose set forth.

In testimony that I claim the foregoing as iny invention I have signed my name, in the presence of two witnesses, this 22d day of May, 1883.

JOHANNES PERSSON.
